Answer:
a) 35°C, the temperature on a hot summer day
b) -11.11°C, the temperature on a cold winter day
c) a 38.88°C fever
d) a furnace operating at 1011.11°C
e) 523.67°F ( theoretically the lowest attainable temperature )
Explanation:
- °C = ( °F - 32 ) / 1.8
- °F = ( 1.8 * °C ) +32
a) 95°F ⇒ °C = ( 95 - 32 ) / 1.8 = 35°C
b) 12°F ⇒ °C = ( 12 - 32 ) / 1.8 = -11.11°C
c) 102°F ⇒ °C = ( 102 -32 ) / 1.8 = 38.88°C
d) 1852°F ⇒ °C = ( 1852 -32 ) / 1.8 = 1011.11°C
e) 273.15°C ⇒ °F = ( 1.8 * 273.15 ) + 32 = 523.67°F
the process goes like this.

Answer is (1) - no reaction.
<em>Explanation;
</em>
Some of you may think this reaction as a single replacement reaction which gives NaBr + F₂ as products.
But, according to the reactivity of the halogens, reactivity decreases from up to bottom of the group. F is placed above Br. Hence, F is more reactive than Br. Hence, Br can't replace F.
Answer:
67.4 % of C₉H₈O₄
Explanation:
To make titrations problems we know, that in the endpoint:
mmoles of acid = mmoles of base
mmoles = M . volume so:
mmoles of acid = 20.52 mL . 0.1121 M
mmoles of acid = mg of acid / PM (mg /mmoles)
Let's determine the PM of aspirin:
12.017 g/m . 9 + 1.00078 g/m . 8 + 15.9994 g/m . 4 = 180.1568 mg/mmol
mass (mg) = (20.52 mL . 0.1121 M) . 180.1568 mg/mmol
mass (mg) = 414.4 mg
We convert the mass to g → 414.4 mg . 1g / 1000mg = 0.4144 g
We determine the % → (0.4144 g / 0.615 g) . 100 = 67.4 %
Answer:
Explanation:
Food wrappers and aluminium wrappers are widely use for packing various eatable items.
For example, in our homes our mother wraps our food for lunch in aluminium foil.
As it helps in keeping the food warm for hours.
Thus, we can conclude that out of the given options, a packaging waste is the garbage collector collecting.
